FLUSHING DEVICE.

Specification of Letters Patent.

Patented June 26, 1917..

Application filed September 13, 1915. Serial 1\To. 50,337.

My invention relates toflushing devices for toilet seats and for otherpurposes, and

the object is to provide simple flushing devices by which the flushingis done with the water under the required pressure of a system of waterworks and more particularly to provide deviceswhich will permit the fiowof water for a limited time and then cut off the fiow of waterautomatically. rldhis provision dispenses with the flushing tank andmakes the flushing equipment much more economical. Other objects andadvantages will be fully explained in the following description and theinvention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of thisapplication.

Figure 1 is a side elevation of the improvements herein described. Fig.2 is a vertical section of the same, showing a vertically moving cup inaction. Fig. 3 is a horizontal section taken on the line :v of Fig. 1.Fig. 4 is a detail view of the rack and sector for operating the valveand the automatic closing devices. Fig. 5 is a bottom plan view of thevalve.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The improved flushing device herein described comprises a valve casing 2communicating with the pipe 1 which is connected with a water supplysource. This casing 2 has a seat 3 for a valve 4 which is provided witha winged stem 5. The valve 4 is raised from its seat by an eccentric 6which is rigid with a shaft 7. The shaft 7 is journaled at the inner endin the side of the valve casing, as shown in Fig. 2, and at the otherend in a stuffing gland 8. The shaft 7 has a shoulder 9 to prevent axialmovement of the shaft, the shoulder 9 engaging an inner shoulder in thestuffing gland casing. Provision is made for divertinga portion of theescaping water and discharging the same out of the side of the cup andby nuts `21.

casing 2. A discharge outlet 10 is formed integral with'and projectswithin the casing and a wing 11 is also formed integral with the casing2 to form a support for the automatic closing devices. The wing 11 isperforated at 12 for the tripping rod 13, the wing or cover 11 thusacting as a guide for the tripping rod. A rack 14 is formed on thetripping rod and a sector 15 is rigid with the shaft 7 and is meshedwith the rack 14. The tripping rod is elevated by a pull cord or cable16 which runs over an idler 17. A pull on the cord 16 will elevate thetripping rod and simultaneously raise the valve 4 by means of theeccentric 6. The idler 17 may be mounted on a bracket 18 which ismounted on the casing 2. The tripv,ping rod 13 is connected with a cup19 by means of a bar 20 which isattached to the The tripping rod is thusadjustably connected to the cup 19. The cup 19 is provided with a valve22 which is prevented from displacement by a cage 23. A trip 24ismounted on the rod 13 and is engaged by a weighted cam 25 which ispivotally mounted in a casing 26 by a pivot bolt or rod 27. When the rod13 is elevated, the trip 24 will ride up on the cam and when the rodreaches its limit of upward travel the trip 24 will rest on the shoulder28 which will support the rod and the cup 19 while the cup 19 is emptyand until the cup is approximately full of water. The size of the cupand the weight of the cam must be adjusted by experiment until the cupcatches the proper amount of water to make the cup drop. The size of thedischarge outlet 10 and the cup must be gaged and timed also to make thecup fall when the fiushing is complete. The casing 26 acts as a guideand protection for the cup 19 and the weighted cam 25. When the cupdrops it will actuate the shaft 7 through the rack 14 and sector 15 andthus let the valve 4 close. When the cup falls the valve 22 will beopened and the water in the cup 19 will be drained through the nipple 31into the pipe 29 which is a continuation of pipe 1. When the cup 19 isnearing the lling point, the trip 24 will bear down on the cam at 28 andslide off so that the cup 19 will fall. A float valve 32 may be looselysuspended from the cam 25 to aid in the release of the trip 25 so thatthe trip will be certain to release the cam at the proper time. Theamount of water to be discharged through the pipes 1 and 29 can befurther regulated by a needle valve 33. More or less water can be madeto pass through the discharge 10 for the purpose of throwing the cup 19.The casing 26 may be mounted on'tlie pipe 29 by means of bands 30 andmay be at taclied to the cover "11 by means of lugs 311. Set screws 35may be used to tighten the bands 30 on the casing 26.

It will be seen that the iiushing devices can be made to flush as longor as short a time as may be necessary or to :ru-n as much water as maybe necessary. It is apparent that various changes may be made in theliushing devices without departing from my invention.

What I claim, is,-

1. In combination, a valve and controllingmeans therefor, comprising ashaft bearing at one end an eccentric adapted on rotation ofthe shaft tounseat the valve and on lthe other end the gear, a rack-bar engagingsaid gear, a cup secured to said rack-bar, means for intercepting aportion of the .discharge from the outlet side of the valve .anddirecting it ,into said cup, swinging gravity tripping` devices foryieldin'gly supporting the cup in .elevated position and adapted topermit the fall of the cup when a predetermined amount of water has beenreceived therein, and means for elevating the rackbar whereby the valveis unseated and the cup elevated.

2. In combination, a valve and controlling means therefor, comprising arocker shaft bearing at one end an eccentric adapted on the rocking ofsaid shaft to unseat said'valve and bearing at the other end and meansfor intercepting a portion of the water discharged by the unseating lofsaid valve and directing the same into said cup to cause said cup todescend and effect the reseating of said valve.

In testimony whereof, I set my hand in the presence of two witnesses,this 3rd day of April, 1914.
